The present work is an extension of our previous analysis of wide-angle \(\pi ^0\)  photoproduction [1]}.
We now apply the handbag mechanism to twist-3 accuracy to wide-angle photoproduction of charged pions and,
in addition, we also investigate wide-angle electroproduction of pions. The latter process with its large
variety of observables may allow for a detailed study of the dynamics of this process and to fix the pion
DAs and form factors in detail. The large \(-t\)  behavior of the transversity form factors encodes the
large-t behavior of the transversity GPDs. The latter is required for the understanding of the parton
densities in the transverse position plane. We think that the present study is timely because of planned
experiments at the Jefferson laboratory.
